For more background on what Soluble Solutions and Irv Wiehe offers in Petroleum Macromolecules please read the following tutorial on the subject. Some of the key points are:

• The primary interaction in petroleum is the van der Waals attraction between polynuclear aromatics
• The low solubility of Asphaltenes is because of a combination of high molecular weight and high aromaticity.
• Petroleum is neither a Colloidal Dispersion nor a Solution but a Hybrid of both.
